Chemical energetics: describe question

Methanol, $\ce{CH3OH(l)}$, burns completely in oxygen to form $\ce{CO2(g)}$ and $\ce{H2O(l)}$.

$$\ce{CH3OH(l) + 3/2 O2(g) -> CO2(g) + 2H2O(l)}$$

The standard enthalpy change of this combustion can be determined from the standard enthalpies of formation of $\ce{CH3OH(l)}$, $\ce{CO2(g)}$ and $\ce{H2O(l)}$.

Describe how you would construct a Hess's law energy cycle for this determination, including the species placed at each level and the enthalpy changes shown on the arrows of the cycle.
